Productbeschrijving
De Dahua SD4A425DB-HNY is een hoogwaardige IP PTZ-domecamera, ontworpen voor veeleisende omgevingen. Met een 4MP-sensor en Smart H.265+-compressie levert hij opnames van hoge kwaliteit en optimaliseert hij de bandbreedte. De 25x optische zoom en Smart IR tot 100 m zorgen voor nauwkeurige bewaking, zelfs in volledige duisternis.
Uitgerust met intelligente functies zoals perimeterbeveiliging, gezichtsdetectie, autotracking en SMD, classificeert deze camera effectief personen en voertuigen, waardoor valse alarmen tot een minimum worden beperkt. PTZ-positionering biedt continue 360° pan en 90° tilt, met snelheden tot 240°/sec.
Hij ondersteunt tot 300 presets, meerdere tours, patronen en scans, wat veelzijdige geautomatiseerde bewaking mogelijk maakt. Hij beschikt over audio en alarmin/uitgang, een MicroSD-slot voor maximaal 512 GB en is compatibel met ONVIF en webbrowsers. Dankzij de IP66-behuizing functioneert het apparaat betrouwbaar buitenshuis, zelfs onder extreme weersomstandigheden.

Nice simple wallet
Color: Derrick Brown, Size: One Size
I purchased this for my husband. It’s one inch shorter than his previous wallet, which had us worried at first. However, it fits all his cards. It has a nice look to it and time of good quality. My husband says he’s happy with it and really likes it.

Expensive, but a well-made slim front pocket wallet
Color: Steven Medium Brown, Size: One Size, Color: Steven Medium Brown, Size: One Size
This is a review for the Fossil “Steven” Front Pocket Bifold Wallet. This wallet measures 4.5 inches x 3.0 inches. It is made with soft-touch leather all around (which feels fantastic), and the build quality is top-notch. It is definitely smaller than a typical wallet, but is still able to hold a good number of cards. I could easily fit about 12 cards into this wallet while still being relatively slim and compact. The wallet is discreet with only a “Fossil” logo that is embossed on the inside. The fabric lining of the cash compartment is treated with an anti-microbial coating. There’s more information about this coating on the manufacturer’s website, but it seems this is to protect against viruses and germs that maybe on cash notes. And while other wallets feature RFID Blocking, this wallet does not claim to do so. This wallet is definitely pricey. And you can easily find other slim wallets for much less. But, I suppose I’m paying for the brand name - and I do like Fossil products. So if you want a brand name wallet that is well-made and slim - this is a good option to consider.

Slim but capable
Color: Steven Medium Brown, Size: One Size
I've had my old wallet for over two decades, it's warren and the edges are starting to fall apart and I thought I'd be proactive and get a new one before it was completely useless.
With all the new slim minimalist designs I was intregeed. This is what I found out, at least for my needs. These new elastic card clips, are nice size wise, are not what the are advertised to be. They are small in your pocket but you need another place for the items you don't use everyday. So as far as being slim and efficient they are misleading. Unless you plan ahead you won't have what you need, say health insurance cards oops forgot them cause I don't use them everyday. Ones with cash clips or elastic bands aren't what they are cracked up to be either. To pull out a bill you need to take all the bills out unfold then and then refold the and squeeze the back in the clip, not covenant.
Next I tried a bi-fold card holder with a money clip. This solved the having everything I needed even if I didn't use it everyday but still had the cash usability issue which required less folding but still needed to pull all the bills out to use. Plus it wasn't any dinner or smaller then my old wallet.
Then I found this wallet, it was pretty much the same as my old one minus one card slot due to the visible ID slot. So in the end this was the perfect wallet for me. Not sure what my old wallet was as the leather is very well worn but I'm guessing it is the same brand.
One other thing this wallet is not scan protected which the other slim wallets were. But you can buy cheap sleeves to place on either side to protect against this if your concerned. One benefit of not having this feature is the ability to keep your key card in your wallet and have it work. Again slim but needing multiple place for your items is not efficient, was not a fan of the carabineer I had to also carry while using the slim wallets.

Great wallet
Color: Steven Medium Brown, Size: One Size
Great and very durable wallet. They are slim, fit well in a pocket, and are thin, unless you have lots of CC and money in it.
